A nurse is collecting data from a newborn who has respiratory distress syndrome and is experiencing respiratory acidosis. Which of the following risk factors predisposes the newborn to respiratory difficulties?
Small for gestational age.
Maternal history of asthma.
Ventricular septal defect.
Cesarean birth.
The Correct Answer is A
Choice A reason:
Small for gestational age (SGA) newborns are at risk for respiratory distress syndrome (RDS) and respiratory acidosis because they have immature lungs that produce less surfactant, which is needed to keep the alveoli open and prevent atelectasis. SGA newborns also have less glycogen stores, which can lead to hypoglycemia and impaired oxygen delivery to the tissues.
Choice B reason:
Maternal history of asthma is not a risk factor for RDS or respiratory acidosis in the newborn. Asthma is a chronic inflammatory disorder of the airways that affects the mother, not the fetus. Maternal asthma can cause complications such as preterm labor, preeclampsia, or intrauterine growth restriction, but it does not directly affect the fetal lung development or function.
Choice C reason:
Ventricular septal defect (VSD) is a congenital heart defect that causes a hole in the wall between the ventricles of the heart. This can result in increased pulmonary blood flow and pressure, which can lead to pulmonary edema and heart failure in the newborn. However, VSD does not cause RDS or respiratory acidosis, which are related to lung maturity and surfactant production.
Choice D reason:
Cesarean birth is not a risk factor for RDS or respiratory acidosis in the newborn. Cesarean birth can increase the risk of transient tachypnea of the newborn (TTN), which is caused by delayed absorption of fetal lung fluid. TTN usually resolves within 24 to 48 hours and does not cause a significant acid-base imbalance in the newborn.

Correct Answer is B
Explanation
Choice A reason:
Administering methylergometrine to the client is not the first action the nurse should take. Methylergometrine is a medication that stimulates uterine contractions and can help reduce postpartum bleeding. However, it can also cause hypertension and should be used with caution in clients with high blood pressure. Furthermore, the nurse should first identify and address the cause of the boggy and deviated fundus before giving any medication.
Choice B reason:
Assisting the client to void is the first action the nurse should take. A full bladder can displace the uterus and prevent it from contracting properly, leading to uterine atony and bleeding.
The nurse should help the client empty her bladder by encouraging her to use the bathroom, providing privacy, running water, or using a bedpan. This can help the uterus return to its normal position and tone.
Choice C reason:
Inserting an indwelling urinary catheter is not the first action the nurse should take. A urinary catheter can be used to drain the bladder if the client is unable to void or has a large amount of residual urine. However, it can also increase the risk of infection and trauma to the urethra
and bladder. The nurse should first try noninvasive methods to help the client void, such as those mentioned in choice B.
Choice D reason:
Obtaining a stat hemoglobin level is not the first action the nurse should take. A hemoglobin level can indicate the extent of blood loss and the need for transfusion or other interventions. However, it is not a priority over restoring uterine tone and preventing further bleeding. The nurse should first assist the client to void and then massage the fundus if it remains boggy.
Correct Answer is ["A","B","E"]
Explanation
Choice A:
Tremors. This is a sign of hypoglycemia in a newborn because low blood sugar can cause shakiness or jitteriness in the muscles. •
Choice B:
Lethargy. This is a sign of hypoglycemia in a newborn because low blood sugar can cause low energy, poor feeding, or lack of interest in eating.
Choice C:
Hunger. This is not a sign of hypoglycemia in a newborn because low blood sugar can actually reduce the appetite or cause feeding difficulties.
Choice D:
Jaundice. This is not a sign of hypoglycemia in a newborn because jaundice is caused by high levels of bilirubin in the blood, not low levels of glucose.
Choice E:
Weak cry. This is a sign of hypoglycemia in a newborn because low blood sugar can affect the vocal cords and the respiratory system, causing a weak or high-pitched cry.
